| Abstract: | Novel chiral N,O-ferrocenyl ligands, in which N and O groups were attached to two different Cp rings of ferrocene, were synthesized from easily available ferrocene, and applied to the asymmetric diethylzinc addition to aldehydes. High chemical yields and good enantioselectivities (up to 90.9% ee) were obtained by using ferrocene ligand 6. |
